To all whom it may concern:

Be it known that I, Jenn F. SHERLOCK, residing at New York, in thecounty and State of New York, have invented certain new and usefulImprovements inEnvelop'e Folders, of which the cation. 7

This invention relates to an improved en'- velope folder, and one of theobjects of the invention is to provide anew and improved device of theabove character which may be manufactured cheaply, with the employmentof a minimum amount of material whileh may be conveniently sent throughthe mai Another object of the invention is to provide an envelope foldeof the above type comprising integrally formed sheet upon which theprinting of the name of the addressee may be positionedon one side ofthe sheet so that when the sheet is folded the printed matter will be onthe inside and concealed and the nam'e ofthe addressee will be visiblefrom the outside. V

Another object of'the invention is to pro vide adevice of the abovecharacter which, when folded, maybe opened in such a way that the partremaining closely simulatesan ordinary billhead or the like. i i 1 Otherobjects and aims of the invention moreior less specific than those abovereferred to, will be in part obvious and in part pointed out in thecoursefof the following description of the elements,v combinations,arrangements .of parts and applications of principles,constitutingtheinvention, and t S ope p ete t-i n co templa ed' il bindicated in the appended claim.

Figure 9 is a I Referring now to the'drawings, wherein similar referencecharacters refer to similar parts throughout the several views thereof,the reference numeral I denotes genera ly the main'portionof the blankco nprises the substantial]y""rectangular parts 2, 3 and 4, and attachedto the part 4 is an end 'flap'5. The parts 3'and 4 and 'theendfiapfi areprovided upon one side with a flap 6," the length of said flap beingco-incident with m ne width f he fi 'effli lrei'fis' 3 and 4 and theflap 5. The part4 is a'lso Ipro-Q vided with a flap 7 upon the oppositeend thereof fromfthe flap '6. Thepart 3 is p o;

the space indicatedat 1 5 whichoccursbe' tween the faces of the parts 2and 3 so'that when the stamp indicated at 16 is placed 'upontheenvelope, it will be engaged by the back face of the part 3 and the backface of the flap 7 whereupon that end of the envelope will be closed bysaid stamp. Inasmuch as the opposite end of the envelope 3 is notpermanently closed, it W111 be readily seen that if the postalauthorities desire to inspect the printed matter upon the'inside of theenvelope it may be readily opened by partially unfolding the flapportions occurring at that end of the device.

V The flap 7, if desired, may also be scored as at 17 so that when thesame is positioned within the envelope as above indicated, said scoringwill lie directly in line with the scou ing 11 upon the parts 2, 3 and4: and the flap 5.

The addressee can open the envelope in the usual way, or, if desired,both ends thereof can be torn off along the scored lines 10 and 11,whereby the substantially rectangular sheet will be provided.

Referring now to the embodiment of my invention illustrated in Figures 6to 9 inclusive, the same comprise a rectangular blank indicatedgenerally at 18, which is divided into four substantially rectangularparts 19, 20, 21 and 22. The parts 21 and 22 areprovided with a flap 23,said flap extending entirely along the lower edge of the flap 21 and aportion only of the lower edge of the part 22. The flap 20 is providedwith a flap 2 L upon its upperedge and the flap 22 is provided with aflap 25 upon'its right hand edge. The part 20 is also provided withalongitudinal slot 26 in its upper right hand corner and with a cutawayportion 27 adjacent its lower right hand corner..

In folding the device from the blank just described, the same is foldedalong the line i 28 and the flap 24: so that the part indicated at29thereof designed to carry the name and address of the addressee, willvcomeopposite the opening 26. A flap 23 is then folded over as indicatedin Figure 7 of the drawings, and in folding this flap it will be noted,forms a pocket 30 designed to receive the upper left hand corner 31 ofthe partially folded-device, the insertion of this corner portion in thesaid pocket operating to-locate the partscomprising that end of the.device in closing position. a V a The device is now, read to be closed,

which is effected by folding the flap 25 along the line 32 andinsertingthe same in the space provided directly underneath the,

cutaway portion of the part 27. The positioning of the stamp indicatedat 33 will fasten the back of the part 20 to the back of the part 25,thus closing that end of the device. The scored lines such as indicatedat 34 and 35 may be provided so that when.

the device is closed the scored lines 34 and the recipient of theenvelope can open the same by merely tearing the same along theseregistering scored lines, and the same can be opened in the usual waybybreaking the seal provided bythe stamp.

it will accordingly be seen that I have provided a device well adaptedto attain, among others, all the ends and objects above pointed out, inan extremely simple and efiicient manner. As will be observed from thestructure above described, while the same is self-contained, eitherembodiment may be readily utilized as the carrier for another piece ofmail matter which-may be inserted between the enclosures formed by theflap portions of the blank. The open ings 8 and 26 providedin the blankmay also be closed bytransparent material such as oiled or waxed paper,if desired.

An envelope folder, comprising a main sheet portion having the samewidth throughout and greater in length] than in width, lines ofperforations running lengthwise at equal distances from the side edgesof the said main portion, an end flap greater in length than the widthof the sheet, a side flap less in length than the lengthof the said mainsheet portion and formed integrally with the said end flap, an insertingflap closiu'ehaving a line of perforations arranged to coincide with oneof said perforated lines of the sheet when the closure flap is inserted,the said, closure flapbeing located upon the opposite side of the sheetfrom the said side flap and having a narrow tapering end locatedadjacent to the said end flap, the said closure flap growing wider as'itextends from the end flap, and a cut-away edge portion located near thewide end of said closure flap whereby when said parts'have been foldedin as described the said cutaway portion lies directly over the widestpart of the closure flap enabling the same to be easily reached andwithdrawn.
